Hi Christopher,
I think I get it now.
Thank you so much for your time!

Re: [yocto] [bitbake-devel] how to store a modification of a bbclass in the poky layer in my own layer.
Layer priority as defined by BBFILE_PRIORITY controls recipe selection, not
bbclass and config file parsing. See the bitbake reference manual for more
detail.

Re: [yocto] [bitbake-devel] how to store a modification of a bbclass in the poky layer in my own layer.
Your layer has to be before poky/meta in BBLAYERS, as that determines
BBPATH, which is how bbclasses and config files are found (much like PATH).
